Top quality Hi-Fi amps and speakers not found anywhere else.Why settle for ordinary sound quality when you can get audiophile / studio quality for the same price?

Valutronic
(Sweden) was started in 1968. We have designed, produced and sold our
own electronics since then, both audio equipment and a vast range of
industrial and automotive electronics as a subcontractor.When it comes to audio products, sound quality and reliability are our first priorities.
We
select the best components and assemble our products with great care.
Our power amplifiers only use discrete ultra-fast small signal
semiconductors and low capacitance HEXFET:s.
Our loudspeaker use carefully selected and tested drivers and we use high-quality filter components.
No corners are cut to increase production speed or profit as mass-producing companies are forced to.
We hand solder our PCB:s to make sure every single solder is OK, to ensure long-lasting quality performance.
When you buy your Hi-Fi from us you get the highest possible quality to price ratio.

Amplifiers:
Our CM-100 power amplifier has only high quality components and the
cicuit design is as good as it gets. No audible distortion, noise or
hum. It took us almost two years (and over 30 prototypes were built)
until we were satisfied with both the sound quality and reliability.
Our customers (both private individuals and sound engineers) usually compare the CM-100 with amplifiers in the 5,000+ USD range.
The amp has a low noise balanced input, dual separated current sources,
a high precision current mirror driver, and low capacitance
HEXFETs. The automatic quiscient current system makes certain that
sound quality will not deteriorate over time. You will never get tired
of the sound.
If you have built electronics before and want to save some money you
can buy only the power amp modules (CM-5017) from us and get the rest
locally. We can also supply a ready-built power supply board with four
rectifying diodes, six electrolytic capacitors, four electronic
self-resetting fuses and input and output screw terminals.

Loudspeakers:
We have designed and built loudspeakers since the company was started,
but in 2004 we decided to take a closer look at a bass
reflex design I stumbled over on a dutch private website. We used the formula from the site to design our first SQ-50
loudspeakers. (SQ stands for Studio Quality and 50 for the RMS
power.)Klick here for the SQ-50 H, here for the SQ-50 L studio quality monitors and here for the orto-acoustical SQ-50C.One
of our first SQ-50 customers was a recording studio in Sweden, and
since then dozens of recording studios and thousands of private
customers have built these wonderful loudspeakers.
After a few years a small cabinet design change was made, and in 2016
there was a
filter
component upgrade and we also upgraded the tweeters. Finally, in 2017
we
upgraded our calculating software and could fine-tune the bass ports to
get an even more firm (not the usual rumbling) and deep bass.
The sound quality of the SQ-50 range is now identical to the Sennheiser studio headphones we use for reference.The
detailed sound, low distortion and wide frequency response (no need for
a subwoofer) puts them among the very best sounding speakers you can
buy.
But at a price you can afford.

We do not recommend using the
loudspeaker drawings and instructions on our site for practical use.
They are here only to give an idea of how easy it is to build your
loudspeakers using our instructions, the size references may not be correct.
So, please wait for the printed instructions that are included in our speaker kits until you start your project.

By
the way, the C variant of the SQ-50īs looks like this. If you live outside Sweden you
might never have seen a loudspeaker looking like this. However, during
the late 1960īs and 1970īs at least 100,000 of the "OA5 MK II" were sold,
the most popular loudspeaker model ever in Sweden.
The SQ-50C is an improved model we have designed ourselves, using modern high-quality components.
These loudspeakers were specifically designed for a normal living room environment.
They have three unique features:
1. Music sounds like if the musicians are playing in your own room.
2. You donīt have to find a "sweatspot". The music is enjoyable all over the room.
3. You can place the speakers where they fit in with your furniture,
instead of moving your furniture to make place for the best positions of
your speakers.

About
us:
We founded our company back in 1966 as "SB-elektronik" but changed the
name to Valutronic in 1984 when we decided to start exporting our
products. We
have built and sold both industrial and commercial electronics for a
long time, but are since the late 1990īs specializing in top quality
audio.
